I try to teach explain basic tasks (copy|paste , resize forms, URLs for web addresses) which never registers or sinks-in beyond our local session. I now understand the meaning of exasperation. I’m on the other side of the fence now but I can reflect on my own mental block(s) — spelling words like haveing, how to insert the bridle, saddle the horse… I just couldn’t/wouldn’t grasp. Now it’s pay-back time. Arrrghhhh!
